3dcl / chartjs-plugin-responsive-downsample Goto Github PK

hi,
After 5 seconds, I add a new sample to the chart. Currently, the chart is refreshed only by zoom/pan the chart. Is there a command refreshing the algorithm?

I am very happy that you took care of the old chartjs-plugin-downsample plugin.

A hint in the README that you added it to npm would be nice, as the first hints on search engines (depending of the search term of course) point to github instead of npmjs.org.

Suggestion for README.md (in front of configuration):

### Installation

```bash
$ npm install chartjs-plugin-responsive-downsample
```

Preview:

Installation

$ npm install chartjs-plugin-responsive-downsample

Can you create a *.min.js file to easy include the plugin without npm? Got a simple project for testing ChartJS and the Plugins for it. And don't know if using NPM is the right for the project.

Hope you understand my issue.

This plugin really looks awesome! Anyway, maybe I am stupid but I cant make it work with ng2-charts:

import { ResponsiveDownsamplePlugin } from 'chartjs-plugin-responsive-downsample';

export class AppComponent {
   // ...
   chartPlugins = [ResponsiveDownsamplePlugin];
   chartOptions: ChartOptions    = {
      aspectRatio:          3,
      responsive:           true,
      legend:               {display: false},
      scales:               {
        xAxes: [
          {
            ticks: {
              maxTicksLimit: 20
            }
          }
        ]
      },
    };

Template:

<canvas baseChart
              [data]="chartData"
              [options]="chartOptions"
              [labels]="chartLabels"
              [plugins]="chartPlugins"
              chartType="line"
      >
</canvas>

There is no error or something, i just doesnt downsample.

Ran into this issue with chartjs-plugin-downsample as well.

When using time series data, Chartjs allows to use 't' instead of 'x' for each data point, but an error is thrown when using this plugin with 't'.

Not a huge problem, just have to switch to 'x', but should be allowed as per the Chartjs docs:
https://www.chartjs.org/docs/latest/axes/cartesian/time.html

Great plugin, btw.

As it seems version 1.1.2 introcued a bug. It works not when I use data with t value, but not anymore with data with x value.
The problem seems to be the line
var i = t.x || t.t;
in the minified version.
t.x || t.t return undefined if t.t is undefined...

I am getting the following error:
chart.downsample.js:204 Uncaught TypeError: Cannot read property 'getTime' of undefined

Probably because I am using chart.min.js, however, I am including also moment.js before that.
